dc.description.abstract

Disease suppression can be seen as a feature to determine healthy soil. From an ecological
standpoint, soil health implies ecosystem stability, diversity, functional connectivity
and resilience in response to a disturbance or stress. Previously suggested
indicators to evaluate soil health and disease suppression have been mainly lists variables
that correlate with the more or less disturbed soils (ranging from conventional
and organic agricultural soils) or favourable conditions to eradicate the disease. This
paper suggests that indicators of soil health and disease suppression could be found by
monitoring the responses of Rhizoctonia solani in common bean and nutrient availability
for the application of a disturbance or stress. Generally these results show a
greater impact on systems (state and private) conventional handling and less impact
on those systems had an agro-ecological management. This approach illustrates the
responses of this fungus with respect to soil management in calcareous soils brown,
after incorporation of a crop on this soil. In this research, the incidence was higher
when incorporated into the soil more of external products and disturbances in the soil
was higher, depending on these soil management in each of the evaluated systems.
Rot caused by Rhizoctonia solani was less severe in agroecological systems compared
to conventional systems which showed most affected although all soils tested
cobdujeron disease greater or lesser degree. These results suggest that the proposed
finding indicators of soil health and disease suppression and resistance to disturbance
or stress approach is promising.
